Army sequestration cuts could affect 17,000 jobs in Georgia

(ATLANTA BUSINESS CHRONICLE) -- If automatic budget cuts of sequestration go into effect, Georgia would see an impact on 17,163 jobs and lose $931 million from its economy, according to a statement from the U.S. Army.?

Impacts on jobs include federal employee furloughs and layoffs, reductions in the contracted workforce because of reduced military investments and construction, and reductions in base operation support, reported an affiliate of the Atlanta Business Chronicle, the Washington Business Journal.

Economic impacts would be the result of sequestration and restrictions on new programs that come with the continuing resolution to fund the government, WBJ reported. ?

NKorea warns US commander in SKorea over drills

PYONGYANG, North Korea (AP) ? North Korea warned the top American commander in South Korea on Saturday of "miserable destruction" if the U.S. military presses ahead with routine joint drills with South Korea set to begin next month.

Pak Rim Su, chief of North Korea's military delegation to the truce village of Panmunjom inside the Demilitarized Zone, sent the warning Saturday morning to Gen. James Thurman, Pyongyang's official Korean Central News Agency said, in a rare direct message to the U.S. commander.

The threat comes as the U.S. and other nations discuss how to punish North Korea for conducting an underground nuclear test on Feb. 12 in defiance of U.N. Security Council resolutions banning Pyongyang from nuclear and missile activity.

North Korea has characterized the nuclear test, its third since 2006, as a defensive act against U.S. aggression. Pyongyang accuses Washington of "hostility" for leading the charge to punish North Korea for a December rocket launch that the U.S. considers a covert missile test.

The U.S. and North Korea fought on opposite sides of the three-year Korean War, which ended in a truce in 1953, not a peace treaty, and left the Korean Peninsula divided by a heavily fortified border monitored by the U.S.-led U.N. Command.

Washington also stations 28,500 American troops in South Korea to protect its ally against North Korean aggression.

South Korea and the U.S. regularly conduct joint drills such as the Key Resolve and Foal Eagle exercises slated to take place next month. North Korea calls the drills proof of U.S. hostility, and accuses Washington of practicing for an invasion.

"You had better bear in mind that those igniting a war are destined to meet a miserable destruction," KCNA quoted Pak as saying in his message to Thurman. He called the drills "reckless."

North Korean leader Kim Jong Un, meanwhile, has been making a round of visits to military units guiding troops in drills and exercises since the nuclear test, KCNA said.

Leaking at Hanford nuclear site worse than thought

Mark Ralston / AFP - Getty Images file

The Hanford site in eastern Washington is considered one of the most contaminated locations on Earth.

By M. Alex Johnson, staff writer, NBC News

The leaking of radioactive liquids at the Hanford, Wash., Nuclear Reservation is more extensive than previously reported, with six storage tanks affected, Washington Gov. Jay Inslee said Friday.

In a conference call with reporters Friday after a meeting with Energy Secretary Steven Chu, Inslee disclosed that six of the 177 tanks were leaking at the nuclear facility in Richland, in eastern Washington about 50 miles southeast of Yakima.?


Inslee said Chu told him that evaluation system of the tank levels wasn't used correctly, raising the prospect that there may be even more leaks. But he said he was told?that there was no immediate threat, a point the Energy Department reiterated in a statement Friday evening.

Hanford ? which houses millions of gallons of radioactive waste left over from plutonium production for nuclear weapons ? is already considered one of the most contaminated sites on Earth, the U.S. government says.

Last week, the U.S. Energy Department said that only one tank was leaking at Hanford.

"We need to get to the bottom of this," Inslee said. He called the disclosure "very disturbing news" and contended that the Energy Department needed a new plan to remove liquid from tanks that can't be repaired.

Sen. Ron Wyden, D-Ore., chairman of the Energy and Natural Resources Committee and an outspoken critic of containment efforts at Hanford, toured the site this week ? before Friday's announcement ? and judged conditions there "an unacceptable threat to the Pacific Northwest for everybody," NBC station KING of Seattle reported.??The Associated Press quoted Tom Towslee, a Wyden spokesman, as saying the senator will be asking the Government Accountability Office to investigate Hanford's tank monitoring and maintenance program.

An estimated 1 million gallons of waste has seeped out of the underground tanks and reached groundwater that will eventually reach the Columbia River, scientists say. The U.S. plans to build a plant to turn the waste into low-level radioactive glass for safe storage, but that facility is years behind schedule for its projected opening in 2019.

In a statement Friday evening, Inslee warned that the federal budget impasse ? which could lead to a "sequestration," or cuts, of?$1.2 trillion in federal spending over 10 years ? made the Hanford predicament even more alarming.

"Frankly, the state Department of Ecology is not convinced that current storage is adequate to meet legal and regulatory requirements," Inslee said.

"With potential sequestration and federal budget cuts looming, we need to be sure the federal government maintains its commitment and legal obligation to the cleanup of Hanford," he said. "To see Hanford workers furloughed at the exact moment we have additional leakers out there is completely unacceptable."

Sequester and public opinion? Advantage Obama. (+video)

With just days until the 'sequester' and its automatic spending cuts kicks in, President Obama seems to have the advantage with high poll ratings and a message seen as more compelling.

By Brad Knickerbocker,?Staff writer / February 23, 2013

President Barack Obama speaks about the sequester as he stands with emergency responders, a group of workers the White House says could be affected if state and local governments lose federal money as a result of budget cuts.

?President Obama?s popularity surges to three-year high?

?Congress Approval Holding Steady at 15 percent.?

RECOMMENDED:?Sequester 101: What happens if $85 billion in cuts hit on March 1

Polls and pundits aren?t everything, of course. Most Americans this weekend likely are far more interested in Sunday night?s Oscar extravaganza.

And most would likely agree with Atlantic associate editor Matthew O'Brien when he writes ? with as much truth as irony ? on the magazine?s web site: ?There is nothing more tedious in the world today than the sequester. The word itself sounds like a prescription sleeping aid.? There is, after all the gnashing of teeth over the ?fiscal cliff? last month, a bit of ?The Boy Who Cried Wolf? here for most people.

Still, if the sequester kicks in, thousands of federal workers could be furloughed, some national park programs could be curtailed, and things could be ?very painful for the flying public,??as Transportation Secretary Ray LaHood warned Friday.

The sequester no doubt will dominate the Sunday morning TV news shows as Republicans and Democrats angle for rhetorical advantage over the sequester?s $85 billion in budget cuts this fiscal year, split evenly between defense and non-defense programs.

At the moment, that advantage seems to be with President Obama and the White House. Just to flesh out those headlines cited above?.

Bloomberg News put it starkly this week: ?President?Barack Obama?enters the latest budget showdown with Congress with his highest job-approval rating in three years and public support for his economic message, while his Republican opponents? popularity stands at a record low.?

Specifically, 55 percent of those polled by Bloomberg last week approve of Obama?s performance in office, his strongest level of support since September 2009. But only 35 percent have a favorable view of the?Republican Party, the lowest rating over the same period. The GOP?s brand slipped six percentage points in the last six months, the poll shows.

Asked who is more to blame for ?what?s gone wrong? in?Washington, those surveyed picked Republicans over Obama 43-34 percent.

Similarly, Gallup finds public approval of Congress ? just 15 percent ? is ?at the low end of the historical spectrum.? It?s not great news for either party, but Democrats have a slight edge in public approval ? 19 percent to 12 percent for the GOP.

Iran announces uranium finds, days before nuclear talks

DUBAI (Reuters) - Days before resuming talks over its disputed atomic program, Iran said on Saturday it had found significant new deposits of raw uranium and identified sites for 16 more nuclear power stations.

State news agency IRNA quoted a report by the Atomic Energy Organisation of Iran (AEOI) which said the reserves were discovered in northern and southern coastal areas and had trebled the amount outlined in previous estimates.

There was no independent confirmation. With few uranium mines of its own, Western experts had previously thought that Iran might be close to exhausting its supply of raw uranium.

"We have discovered new sources of uranium in the country and we will put them to use in the near future," Fereydoun Abbasi-Davani, head of the AEOI, was quoted as saying at Iran's annual nuclear industry conference.

The timing of the announcement suggested Iran, by talking up its reserves and nuclear ambitions, may hope to strengthen its negotiating hand at talks in Kazakhstan on Tuesday with the United States, Russia, China, Britain, France and Germany.

Diplomats say the six powers, known as the P5+1, are set to offer Iran some relief from international sanctions if it agrees to curb its production of higher-grade enriched uranium.

The West says Iran's enrichment of uranium to a fissile purity of 20 percent demonstrates its intent to develop a nuclear weapons capability, an allegation the Islamic republic denies.

FROM MINE TO CENTRIFUGE

The enriched uranium required for use in nuclear reactors or weapons is produced in centrifuges that spin uranium hexafluoride gas (UF6) at high speeds. The UF6 is derived from yellow cake, a concentrate from uranium ore discovered in mines.

Iran's reserves of raw uranium now stood at around 4,400 tonnes, taking into account discoveries over the past 18 months, IRNA quoted the report as saying.

In another sign that Iran is intent on pushing forward with its nuclear ambitions, the report also said 16 sites had been identified for the construction of nuclear power stations.

It did not specify the exact locations but said they included coastal areas of the Gulf, Sea of Oman, Khuzestan province and the Caspian Sea.

Iranian authorities have long announced their desire to build more nuclear power plants for electricity production. Only one currently exists, in the southern city of Bushehr, and that has suffered several shutdowns in recent months.

The announcements could further complicate the search for a breakthrough in Kazakhstan, after three unsuccessful rounds of talks between the two sides in 2012.

"We are meeting all of our obligations under the nuclear Non-Proliferation Treaty and we should be able to benefit from our rights. We don't accept more responsibilities and less rights," Saeed Jalili, Iran's chief nuclear negotiator, was quoted as telling Saturday's conference.

In what Washington has called a provocative move, Iran is also installing new-generation centrifuges, capable of producing enriched uranium much faster, at a site in Natanz in the centre of the country.

Western diplomats say the P5+1 will reiterate demands for the suspension of uranium enrichment to a purity of 20 percent, the closure of Iran's Fordow enrichment plant, increased access for International Atomic Energy Agency inspectors and agreement to address concerns on existing uranium stockpiles.

In return, the latest embargoes on gold and metals trading with Iran would be lifted. Iran has criticized the offer and says its rights need to be fully recognized.

"If the P5+1 group wants to start constructive talks with Tehran it needs to present a valid proposal," said Jalili. "It needs to put its past errors to one side ... to win the trust of the Iranian nation."

In a statement issued before the Iranian announcement, German Foreign Minister Guido Westerwelle said the six-power group wanted to enter a 'substantial negotiation process' over Tehran's nuclear program.

"The talks in Almaty are a chance which I hope Iran takes," he said.

Fri, 22 Feb 2013 05:59 CST

21 February 2013 - Brittney Mcconnell, Pleasanton, CA 22:30 PST
Between 5-10 seconds duration. Lime green color with orange trail. Sun white hot in brightness but also lime green. No fragmentation observed, just the flaming trail behind it. It wasn't heading straight down but angled at about 30 degrees. I estimate that it landed in the Pleasanton/Sunol area.
21 February 2013 - Mark S. Dobkin, Costa Mesa, CA USA, Approx. 22:30 PST
2-3 seconds duration - I was facing West. East-West direction. Bright white ball of fire, then broke up. I was stationary in my car, so did not hear any sound. As bright as moon, but not as large. Considerably larger than Venus. Fragmentation observed. Fairly large. One of the largest I have seen.
21 February 2013 - Chloe Michaels, Thousand Oaks, CA, USA 10:30 PST
2-3 seconds duration. I could only view it from my window. North-West direction. It was a white ball and streak of light, with a tail. As bright as the moon.
21 February 2013 - Kris, Los Angeles, CA 22:50
2/3 seconds duration. North-West direction. Green color, as bright as Venus. I'm curious as to what that was.
21 February 2013 - Jasmine Brown, Los Angeles, CA, U.S. 22:35
7 seconds duration. I was facing West. It went from orange color to bright blue, heading straight down. I couldn't hear any sound. The piece itself looked as though it came off of something. It went so fast, I was pulling out of the parallel driving spot to head for work. I turned and went the other way in case it hit the ground. I've seen a few fly across but this was heading straight to the ground without disappearing in mid-air.
21 February 2013 - Nick Bishop, Sacramento, CA, United States, Approx 22:50
2 seconds duration. I was looking south in a vehicle. Meteor started at approx 165 degrees and moved nearly directly vertically downwards. Maybe 5 degrees of horizontal movement to the west. Green (exact color of burning copper), with orange/red debris trailing behind, which rapidly (1/4 second) burnt out. Brighter than the Sun, less bright than the moon. Very rapid movement, hard to judge size but it seemed to be quite small. Object totally disintegrated before reaching the horizon.
21 February 2013 - Joe, Fresno, CA, USA 22:31 PST
3 seconds duration. I was driving, traveling west. I was looking forward, but something suddenly caught the corner of my eye out my driver's side window, which was facing outward south. The meteor appeared to be coming from the east/southeast, headed west/northwest. Fluorescent green, no noise. As bright as the moon. There didn't appear to be any fragmentation. It had a long tail. Very large object, equivalent to approximately 1/6 the size of the moon.

All eyes on Venezuelan hospital, no sign of Chavez

CARACAS, Venezuela (AP) ? At Caracas' military hospital, the only outward signs that President Hugo Chavez is a patient inside are the motorcades that come and go and the soldiers standing guard, some of them wearing red berets.

A poster with a large photo of Chavez smiling sits atop the Dr. Carlos Arvelo Military Hospital, but it has been there since long before the socialist leader was admitted upon his return from his latest cancer treatment in Cuba.

Some of the president's supporters shout "Viva Chavez!" and "He's back!" as they drive past the hospital, which this week has become the new center of attention in Chavez's 21-month-long cancer struggle.

The government provided an update on Chavez's condition Thursday night, saying that he remained at the hospital and that "the medical treatment for the fundamental illness continues without presenting significant adverse effects."

Information Minister Ernesto Villegas read the statement on television, saying that a "respiratory insufficiency" that arose in the weeks after the surgery "persists and its tendency has not been favorable, thus it continues to be treated." The government has said Chavez is breathing through a tracheal tube.

"The patient remains in communication with his relatives, with the political team of his government and in close cooperation with his medical team," Villegas said, adding that Chavez "keeps clinging to Christ, with a maximum will to live."

The government hasn't released a single photo of Chavez since his arrival in Caracas on Monday, and that has led some Venezuelans to question whether he's actually in the hospital. Others insist he is there, just out of sight while undergoing treatment.

"There, where you see that balcony, the president is there," said Juan Carlos Hernandez, a street vendor who pointed to the ninth floor, where Chavez is said to be staying.

Hernandez, who sells snacks from a stand with a parasol, said he used to work as a military police officer and provided security at the hospital from 2004 to 2006. He said the ninth floor has a special wing with various rooms where important people are typically taken for treatment, including generals and other military officers.

The special wing of the hospital has its own private elevator, Hernandez said. "The patients are more protected because not everybody passes by."

Caravans of SUVs escorted by troops on motorcycles have arrived and left in recent days, carrying officials including Vice President Nicolas Maduro and National Assembly President Diosdado Cabello, who are among the few who say they have seen Chavez at the hospital.

Among the luxury vehicles bringing visitors was a metallic green Bentley, and those stopping by the hospital have reportedly included the president's relatives.

The government hasn't given details of any visits with Chavez at the hospital, and Bolivian President Evo Morales said Wednesday that he had met only with relatives and doctors but was unable to see Chavez himself when he visited the hospital. Speaking at the United Nations, Morales said Chavez "is in a very difficult spot with his health."

The Venezuelan leader has been undergoing cancer treatment in Cuba on and off since June 2011. He has said he has had tumors removed from his pelvic region and has undergone chemotherapy and radiation treatment.

Throughout the treatments, Chavez has not revealed the type of cancer or the location where tumors have been removed.

He hasn't spoken publicly since before his latest surgery in Cuba, on Dec. 11. The government has recently said that Chavez is undergoing more treatment for his illness but has not specified the sort of treatment.

Hospital employees declined to comment about Chavez, saying only that the floor where the president is being treated is under tight security. The hospital administration did not respond to calls seeking comment.

In addition to treating the president, the hospital continues to provide medical care to hundreds of other patients every day.

The hospital opened in 1962 and is named after Carlos Arvelo, a doctor who participated in Venezuela's independence struggle. It has a capacity of 1,000 beds and says it treats about 29,000 patients a year, of whom only about 7 percent are military personnel and the rest are civilians. The hospital has about 4,000 employees.

It is one of the main public hospitals in Caracas, and provides treatment largely to poor and middle-class patients. The hospital has one of the country's most modern intensive care units as well as an advanced kidney transplant unit.

When Chavez's return to Caracas was announced Monday, his supporters gathered outside the hospital to celebrate while holding photos of him. But as the days have passed, their numbers have dwindled.

Journalists and television cameras at the entrance have become one of the few signs of anything unusual going on, in addition to the soldiers, police and members of the presidential guard standing watch at entrances, in hallways and on nearby streets.

Juan Bonaire, who works at a bakery across the street, said that apart from the stepped-up security, the area around the hospital looks much the same as always.

The surrounding neighborhood is filled with modest homes and old, weathered buildings where there are businesses including restaurants and shops that cater to patients and hospital workers.

Near the hospital, people put up a banner Thursday with a photo of the president and the slogan: "Chavez is not a man. He is a nation that advances. We will live and triumph."

Sens. Collins, King tour Maine shipyards ahead of major military cuts

The Pentagon says Maine could be facing about $41 million in Defense Department civilian payroll cuts if automatic government spending cuts kick in March 1.

Maine U.S. Sens. Susan Collins and Angus King toured Bath Iron Works Thursday morning and talked about the potential cuts.

They voiced their support for the workers at BIW, and said they hope a temporary reprieve could be reached to avoid the so called "sequester."

"It's an embarrassment that our government has put us in this position," said King

Hundreds of technical jobs at the ship building facility hang in the balance if Congress can't agree on a defense department budget.?

A union representative for technical employees said several hundred BIW workers are anxious and frustrated with the prospect of losing their jobs within the next six to nine months.

"We will continue to do everything we can to ensure we have the funding to build these ship," said Collins.

According to the Navy, 1,121 temporary workers would lose their jobs nationwide, mostly in shipyards. And if Congress fails to negotiate on a plan, the USS Miami repairs at Portsmouth Naval Shipyard could be deferred.

Defense Secretary Leon Panetta told Congress on Wednesday that if a budget deal isn't reached, he may have to shorten the workweek for the "vast majority" of the Defense Department's 800,000 civilian workers. They'd lose one day of work per week, or 20 percent of their pay, for up to 22 weeks, probably starting in late April.
?? ?
Pentagon figures show its civilian payroll in Vermont for the 2012 fiscal year was $486 million and about $445 million for 2013.
?? ?
The biggest potential civilian payroll losses would be in Virginia, California, Maryland, Texas and Georgia.

Collins and King were scheduled to visit the Portsmouth Naval Shipyard Thursday afternoon.

GM boosting sales through failing subprime auto loans | Washington ...

AP

AP

BY: Bill McMorris

Bailout recipient General Motors leads the world in car sales thanks in part to subprime auto lending that may cause a fiscal calamity,?financial and auto industry observers fear.

?You have the government trying to sell the bailout and this recovery and they?ve allowed, encouraged GM to?revive itself off the back of subprime lending,? said Ed Niedermeyer, auto industry consultant.

GM Financial (GMF), the company?s in-house financing arm, reported that delinquencies grew by about $200 million to $933 million in 2012, according to GM?s annual SEC filing.

Delinquent contracts at GM now represent 8.5 percent of all auto loans?higher than delinquencies at Ford, Toyota, and Honda combined.

All four companies have in-house financing arms that lend money to purchasers. GM?s structure differs from its competitors because it focuses primarily on subprime borrowers, while customers with higher credit scores opt for financing from Ally Bank.

?When you talk about our delinquency rate, GM Financial?s is higher than the industry average of captive lenders because 85 percent of our portfolio is subprime, whereas the portfolios of other captive lenders are predominantly prime,? GM Financial spokeswoman Chrissy Heinke said. ?So, it?s not an apples to apples comparison.?

GM?s prime borrowers fall into delinquency at the industry average. Ally reported 1.6 percent in delinquencies in the quarter ending Sept. 30, 2012, its most recently available SEC filing.

General Motors is doubling down on the subprime strategy. Only 4 percent of GMF borrowers had credit scores above 660 in 2012, compared to nearly 8 percent in 2011.

Additionally, GMF now represents more than 7 percent of the entire subprime market and its number of subprime borrowers may be even higher, according to company executives.

?GM Financial percentage of GM?s U.S. consumer subprime financing and leasing was 20 percenton the [4th] quarter,? GM CFO Daniel Ammann said in a Feb. 14 conference call.

President Barack Obama has repeatedly blamed subprime lending practices in the housing industry for the 2008 crash.?

?We all know the story by now: Mortgages?sold to people who couldn?t afford them, or even sometimes understand them,? he told a Kansas audience in 2011. ?Banks and investors?allowed to keep packaging the risk and selling it off. Regulators who were supposed to warn us about the dangers of all this, but looked the other way or didn?t have the authority to look at all. ? It combined the breathtaking greed of a few with irresponsibility all across the system. And it plunged our economy and the world into a crisis.?

The administration created the Consumer Financial Protection Bureau (CFPB) to address the perceived lack of enforcement. The CFPB serves as a watchdog on complicated financial instruments such as subprime mortgages.

However, subprime auto loans are exempted from CFPB oversight thanks to opposition from industry interests.

?They didn?t want to be subject to the same regulations as banks,? one industry source said. ?The administration and Democrats in Congress were more than willing to hand over the keys. They knew what a stalled auto sales market would mean for how people viewed the bailouts.?

Obama made GM?s sales growth a centerpiece of his campaign during stops in Ohio and Michigan. The car company used flexible financing, pricing incentives, and other discounts to drive up volume, selling more than 9 million vehicles last year.

?Car sales have been the one economic indicator that the Obama administration has repeatedly pointed to as sign of recovery; we?re creating a bubble in order to make a government pet project look viable,? Niedermeyer said. ?GM is using subprime to move cars out doors but it won?t last forever, and eventually the music is going to stop and we?re going to be back where we found them before the bailout.?

The growth in car sales has not bolstered the company?s standing in domestic sales. GM?s market share fell to 17.5 percent, down from 18.8 percent when it launched its initial public offering in 2010.

General Motors still owed $21.6 billion on its $49.5 billion bailout as of Jan. 30.

Cargill settles NAFTA dispute with Mexico

Cargill Inc has reached a settlement with Mexico in a dispute that resulted in a $77 million arbitration award for the U.S. agribusiness company, according to court documents filed Thursday.

A North American Free Trade Agreement arbitration tribunal awarded Cargill the sum in 2009 over trade barriers the company said Mexico erected against high-fructose corn syrup from 2002 to 2007.

Terms of the settlement, reached February 5, were not disclosed. The settlement was detailed in papers filed in U.S. District Court in New York, where Cargill had filed a lawsuit to enforce the arbitration award.

A spokeswoman for Cargill had no immediate comment. A representative for Mexico's Economy Ministry did not respond to a request for comment.

Cargill filed its claims against Mexico in 2005 under Chapter 11 of NAFTA, which allows companies to sue countries that are members of the treaty for actions that affect their investments.

In 2009, the tribunal awarded Mexico $77.3 million plus interest and costs. In May 2012, the Supreme Court of Canada, the country where the original NAFTA panel was held, let the award stand.

Cargill in November filed the federal lawsuit in New York to enforce the award. It said with interest the award was now worth $94.6 million.

The case is Cargill, Incorporated v. United Mexican States, U.S. District Court, Southern District of New York, 12-08225.

New imaging device is flexible, flat, and transparent

Feb. 20, 2013 ? Digital cameras, medical scanners, and other imaging technologies have advanced considerably during the past decade. Continuing this pace of innovation, an Austrian research team has developed an entirely new way of capturing images based on a flat, flexible, transparent, and potentially disposable polymer sheet. The team describes their new device and its possible applications in a paper published February 20 in the Optical Society's (OSA) open-access journal Optics Express.

The new imager, which resembles a flexible plastic film, uses fluorescent particles to capture incoming light and channel a portion of it to an array of sensors framing the sheet. With no electronics or internal components, the imager's elegant design makes it ideal for a new breed of imaging technologies, including user interface devices that can respond not to a touch, but merely to a simple gesture.

"To our knowledge, we are the first to present an image sensor that is fully transparent -- no integrated microstructures, such as circuits -- and is flexible and scalable at the same time," says Oliver Bimber of the Johannes Kepler University Linz in Austria, co-author of the Optics Express paper.

The sensor is based on a polymer film known as a luminescent concentrator (LC), which is suffused with tiny fluorescent particles that absorb a very specific wavelength (blue light for example) and then reemit it at a longer wavelength (green light for example). Some of the reemitted fluorescent light is scattered out of the imager, but a portion of it travels throughout the interior of the film to the outer edges, where arrays of optical sensors (similar to 1-D pinhole cameras) capture the light. A computer then combines the signals to create a gray-scale image. "With fluorescence, a portion of the light that is reemitted actually stays inside the film," says Bimber. "This is the basic principle of our sensor."

For the luminescent concentrator to work as an imager, Bimber and his colleagues had to determine precisely where light was falling across the entire surface of the film. This was the major technical challenge because the polymer sheet cannot be divided into individual pixels like the CCD camera inside a smartphone. Instead, fluorescent light from all points across its surface travels to all the edge sensors. Calculating where each bit of light entered the imager would be like determining where along a subway line a passenger got on after the train reached its final destination and all the passengers exited at once.

The solution came from the phenomenon of light attenuation, or dimming, as it travels through the polymer. The longer it travels, the dimmer it becomes. So by measuring the relative brightness of light reaching the sensor array, it was possible to calculate where the light entered the film. This same principle has already been employed in an input device that tracks the location of a single laser point on a screen.

The researchers were able to scale up this basic principle by measuring how much light arrives from every direction at each position on the image sensor at the film's edge. They could then reconstruct the image by using a technique similar to X-ray computed tomography, more commonly known as a CT scan.

"In CT technology, it's impossible to reconstruct an image from a single measurement of X-ray attenuation along one scanning direction alone," says Bimber. "With a multiple of these measurements taken at different positions and directions, however, this becomes possible. Our system works in the same way, but where CT uses X-rays, our technique uses visible light."

Currently, the resolution from this image sensor is low (32x32 pixels with the first prototypes). The main reason for this is the limited signal-to-noise ratio of the low-cost photodiodes being used. The researchers are planning better prototypes that cool the photodiodes to achieve a higher signal-to-noise ratio.

By applying advanced sampling techniques, the researchers can already enhance the resolution by reconstructing multiple images at different positions on the film. These positions differ by less than a single pixel (as determined by the final image, not the polymer itself). By having multiple of these slightly different images reconstructed, it's possible to create a higher resolution image. "This does not require better photodiodes," notes Bimber, "and does not make the sensor significantly slower. The more images we combine, the higher the final resolution is, up to a certain limit."

The main application the researchers envision for this new technology is in touch-free, transparent user interfaces that could seamlessly overlay a television or other display technology. This would give computer operators or video-game players full gesture control without the need for cameras or other external motion-tracking devices. The polymer sheet could also be wrapped around objects to provide them with sensor capabilities. Since the material is transparent, it's also possible to use multiple layers that each fluoresce at different wavelengths to capture color images.

The researchers also are considering attaching their new sensor in front of a regular, high-resolution CCD sensor. This would allow recording of two images at the same time at two different exposures. "Combining both would give us a high-resolution image with less overexposed or underexposed regions if scenes with a high dynamic range or contrast are captured," Bimber speculates. He also notes that the polymer sheet portion of the device is relatively inexpensive and therefore disposable. "I think there are many applications for this sensor that we are not yet aware of," he concludes.

A NATO-led force can help stabilize Libya and North Africa

From Jason Pack & Karim Mezran, New Atlanticist:? From Cairo on the Nile to Tunis on the Mediterranean, a political vacuum has descended across North Africa. The Arab Spring ushered in new freedoms, but it also weakened existing state structures and unleashed a cultural and political free-for-all, favorable to mobilization, assassinations and propagation of extremist ideology. The region?s newly elected governments are rapidly failing to produce results, put aside internecine bickering or form grand coalitions. Despite their democratic legitimacy, they are losing the consent of their populations. Amid this chaos, North Africa?s Saharan underbelly, the Sahel, is on the verge of replacing the Afghanistan/Pakistan border as the major global safe haven for terrorist networks. Libya is both at the root of these problems and the key to the solution.?

The spread of Salafist and jihadist groups, the war in Mali and the recent terrorist attack in Algeria are all direct consequences of the overthrow of Muammar Qadhafi. Paradoxically, international action in support of the Libyan people led to this whole mess, yet it is also the key to resolving it.

At present, Libya?s new central government is so weak that swaths of the country are ungoverned space ? local authorities mediate disputes and the revolutionary militias dominate what few security institutions exist. Radicalized jihadists come and go as they please and heavy artillery from Qadhafi?s stockpiles is sold to the highest bidder. . . .

To help [Prime Minister Ali] Zidan bring stability, win back the trust of his people and cement his legitimate authority against [president of Libya?s parliament Mohamed] Magarief?s overreach, a new international coalition must help the Libyan government construct a coherent security apparatus. On Tuesday, representatives of the major Arab and Western powers ? including the U.S. ? met in Paris under the aegis of the Support Libya conference and finally agreed to ?the rapid deployment of European experts? to train and rebuild Libyan security forces. To be effective, the whole process must be initiated, owned and managed by the Libyans, while building upon the international community?s role as guarantors of the Libyan revolution. . . .

Since multilateral engagement won the war, it is now time to reconstitute the coalition to win the peace. Tuesday?s decision could be the turning point. Success is achievable only if the right type of training is paired with high-level political engagement and if America invests significant diplomatic and technical resources.

The coalition should start by training a new security force, approximately 6,000 strong. NATO countries should lead, but key Arab allies should also be given a prominent role. This force should receive on-the-job training while securing the country?s borders and physical institutions. American know-how is needed to build an army capable of handling diverse threats from nonstate actors, leaving the Europeans to focus on training the police. . . .

Even the speedy French-led dispersal of Islamist forces in Mali cannot provide long-term gains if Libya remains an ungoverned space. Unrest in neighboring Tunisia ? long thought of as the success story of the Arab Spring ? threatens to undermine the very model of transition from dictatorship to constitutional democracy in line with Islamic cultural norms. Libya has the wealth, educated populace and strategic location to succeed. It is up to the Libyans and their allies to close ranks. Libya is truly the linchpin to any comprehensive strategy to bring stability to North Africa and the Sahel.

Obama minimum wage plan renews economic debate

Chart shows states with minimum wages higher than the Federal wage

Chart shows states with minimum wages higher than the Federal wage

(AP) ? President Barack Obama says increasing the minimum wage to $9 an hour and tying future increases to inflation will raise the incomes of millions living in poverty and spur job growth.

Business groups are not so sure. They complain that boosting the federal rate from $7.25 an hour would discourage employers from hiring new workers, hurting the very people Obama aims to help.

In all, 19 states and the District of Columbia have minimum wages set above the federal rate of $7.25. Obama highlighted that disparity in his State of the Union address on Tuesday night.

Ten of those states make annual cost-of-living adjustments, including Washington state, where workers earn at least $9.19 an hour. That's the highest minimum wage in the country.

Four biggest moments from ?The Ultimate Fighter?

Last week's "The Ultimate Fighter" knockout was memorable, so how do you try to top that? A rap battle, some blood and a hospital gown.

Adam Cella still in his hospital gown. Fresh off last week's stunning knockout by Uriah Hall, Cella returned to the TUF house still wearing his hospital gown. He was not seriously injured, but did have to go over the details of the fight with teammates to know exactly what happened. He also nearly joined Hall in the shower to congratulate him.

Rap battle? Rap battle. Gilbert Smith made fun of Kevin Casey for his rapping, specifically this video.

This turned into a rap battle with several fighters participating, and Casey emerging as the clear winner.

Don't mess with people's sleep. When power went out at the TUF house, Team Sonnen thought it would be a good idea to run into Collin Hart's room and throw toilet paper at him as he slept. No, I don't get it, either. But with Hart preparing to meet Casey, he did not want his sleep messed with. Hart was so heated about it that he put up his middle finger during the post-weigh in staredown.

Hart breaks Casey. In a bloody battle, Hart starts with a jumping kick and follows it with a takedown. From there, Hart controls the entire fight. UFC president Dana White is impressed, saying, "It's almost like he broke him." Hart takes the fight 20-18 on every card.

With Hart's win, Team Jones wrested away control from Team Sonnen. The next bout is Bubba McDaniels and Kelvin Gastelum. What did you think of this week's episode? Speak up in the comments, on Facebook or on Twitter.

What Would Happen if Asteroid 2012 DA14 Hit Earth?

There is absolutely no chance that asteroid 2012 DA14 will hit Earth when it makes its closest approach on Friday (Feb. 15), but many other asteroids like it have made a crash landing on the planet in the past.

Although the 150-foot (45 meters) space rock is nowhere near as large as the asteroid thought?thought to have killed off the dinosaurs?? that behemoth was likely about 6 miles (10 kilometers) wide ? it could still cause some serious damage, experts say.

"The asteroid is about 150 feet in diameter and has a mass estimated at about 143,000 tons," NASA astronomer Don Yeomans wrote in a Feb. 9 opinion piece for The New York Times. "Should an object of that size hit Earth, it would cause a blast with the energy equivalent of about 2.4 million tons ? or 2.4 megatons ? of TNT explosives, more than 180 times the power of the atomic blast that leveled Hiroshima."

Yeomans and his colleagues at NASA have said that an asteroid of similar size to 2012 DA14 probably caused the so-called "Tunguska Event"?over Siberia's Tunguska River in 1908.

In that case, a 100-foot-wide (30 meters) asteroid exploded after it entered Earth's atmosphere, leveling 825 square miles (2,137 square km) of trees in the region.?If asteroid 2012 DA14?were to strike the planet, it would probably behave in much the same way as the Tunguska object, NASA scientists have said.

The asteroid's impact wouldn't cause a worldwide catastrophe, Yeomans said, but it would be a regional disaster.

Tunguska-like airbursts occur when an asteroid falls through Earth's atmosphere, superheating the rock and causing it to explode. The violent detonation creates intense blasts of hot wind and gas that destroys any organic material on the ground.

These kinds of impacts aren't too uncommon. In late 2009, an asteroid released the equivalent of 110,000 pounds of TNT over Indonesia when it exploded over the island nation. That space rock was estimated to be 16 to 33 feet (5 to 10 m) in diameter, according to a NASA report.

While Earth will continue to be pummeled by asteroids for the duration of its existence, we're unlikely to see a civilization-threatening impact anytime soon. NASA researchers have mapped out the paths for?90 percent of the Earth-destroying near-Earth objects,?and so far they've found none on a collision course in the foreseeable future.

Pope celebrates last public Mass as pontiff

VATICAN CITY (AP) ? Beginning a long farewell to his flock, a weary Pope Benedict XVI celebrated his final public Mass as pontiff, presiding over Ash Wednesday services hours after a bittersweet audience that produced the extraordinary scene of the leader of the world's billion Catholics explaining himself directly to the faithful.

The mood inside St. Peter's Basilica was somber during the Mass, as if the weight of Benedict's decision and the finality of his pontificate had finally registered with the thousands present. The basilica erupted in a rousing standing ovation as Benedict exited for the last time as pope, bringing tears to the eyes of some of those closest to him.

"We wouldn't be sincere, Your Holiness, if we didn't tell you that there's a veil of sadness on our hearts this evening," Cardinal Tarcisio Bertone, Benedict's longtime deputy, told the pope at the end of the service, his voice breaking.

"Thank you for having given us the luminous example of the simple and humble worker in the vineyard of the Lord," Bertone said, quoting Benedict's words when he first appeared on the loggia overlooking St. Peter's Square after he was elected pope.

Smiling and clearly moved, Benedict responded, "Grazie. Now let us return to prayer" ? his words bringing to an end several minutes of thundering applause. Then, in a rare gesture and sign of respect, the bishops removed their mitres.

"Viva il papa!" the crowd yelled as the pope stepped off the altar, assisted by two clergymen, and departed St. Peter's aboard a moving platform to spare him the long walk down the aisle.

Ash Wednesday marks the start of Lent, the most solemn season on the church's liturgical calendar that ends with Holy Week, which commemorates the death of Christ and his resurrection on Easter Sunday. By this Easter, on March 31, the church will likely have a new pope.

The scene was festive earlier in the day, when Benedict took the extraordinary step of speaking directly to his flock about why he had broken with 600 years of tradition and decided to retire on Feb. 28.

"As you know, I have decided to renounce the ministry that the Lord gave to me on April 19, 2005," Benedict said, to warm applause. "I did this in full liberty for the good of the church."

He thanked the faithful for their prayers and love, which he said he had "physically felt in these days that haven't been easy for me." And he asked them to "to continue to pray for me, the church, and the future pope."

Benedict looked tired but serene as he basked in a standing ovation when he entered the packed hall for his traditional Wednesday catechism lesson. His speech was interrupted repeatedly by applause, and many in the audience of thousands had tears in their eyes.

A huge banner reading "Grazie Santita" ("Thank you Your Holiness") was strung up and a chorus of Italian schoolchildren serenaded him with one of his favorite hymns in German ? a gesture that won over the pope, who thanked them for singing a piece "particularly dear to me."

He appeared wan and spoke softly, but his eyes twinkled at the welcome.

"He gave us eight wonderful years of his words," said Ileana Sviben, an Italian from the northern city of Trieste. "He was a wonderful theologian and pastor."

The Rev. Reinaldo Braga Jr., a Brazilian priest studying theology in Rome, said he, too, was saddened when he first heard the news.

"The atmosphere was funereal but nobody had died," he said. "But then I realized it was a wise act for the entire church. He taught the church and the world that the papacy is not about power, but about service."

It was a sentiment the retiring Benedict himself emphasized Wednesday, saying the "path of power is not the road of God."

Benedict 's decision has placed the Vatican in uncharted waters: No one knows what he'll be called or even what he'll wear after Feb. 28.

The Vatican revealed some details of that final day, saying Benedict would attend a morning farewell ceremony with his cardinals and then fly by helicopter at 5 p.m. to the papal summer retreat at Castel Gandolfo.

That means Benedict will be far from the Vatican when he ceases being pope at 8 p.m. ? a deadline decided by the pope himself because that's when his normal workday ends.

Vatican spokesman the Rev. Federico Lombardi said no formal or symbolic act was needed to make his resignation official, because Benedict has already done all that was required to resign by affirming publicly he had taken the decision freely.

Benedict's final official acts as pope will include audiences with the Romanian and Guatemalan presidents this week and the Italian president on Feb. 23.

To assure the transition goes smoothly, Benedict made an important appointment Wednesday, naming the No. 2 administrator of the Vatican city state, Monsignor Giuseppe Sciacca, as a legal adviser to the camerlengo.

The camerlengo, or chamberlain, helps administer the Vatican bureaucracy in the period between Benedict's resignation and the election of a new pope. The current camerlengo is Bertone, the Vatican secretary of state.

He and the dean of the College of Cardinals, Cardinal Angelo Sodano, will have a major role in organizing the conclave, during which the 117 or so cardinals under the age of 80 will vote on who should succeed Benedict.

The Vatican has made clear that Benedict will play no role in the election of his successor, and once retired, he will live a life of prayer in a converted monastery on the far northern edge of the Vatican gardens.

His continued presence within the Vatican walls has raised questions about how removed he really will be from the life of the church. Lombardi acknowledged that Benedict would still be able to see friends and colleagues.

"I think the successor and also the cardinals will be very happy to have very nearby a person that best of all can understand what the spiritual needs of the church are," Lombardi said.

Benedict is expected, however, to keep a low public profile.

As a result, Benedict's final public appearances ? his last general audience will be Feb. 27 ? are expected to draw large crowds for what may well be some of the last speeches by a man who has spent his life ? as a priest, a cardinal and a pope ? teaching and preaching.

And they will also give the faithful a way to say farewell under happier circumstances than when his predecessor, Pope John Paul II, died in 2005.

Wisconsin scientists help search for alien life

MADISON, Wis. (AP) ? Scientists at the University of Wisconsin-Madison are helping search for evidence of alien life not by looking into outer space, but by studying some rocks right here on Earth.

Some of the rocks are up to 3.5 billion years old. The scientists are looking for crucial information to understand how life might have arisen elsewhere in the universe and guide the search for life on Mars one day.

"There's a story always hidden in rocks," said geoscientist Clark Johnson, the lead investigator for the Wisconsin Astrobiology Research Consortium. "... It's up to (geologists) to be clever enough to find the tools that we need to interrogate those rocks to find what story they preserve."

The project is funded through NASA, which provided a $7 million, five-year grant that started in January. It was the group's second five-year, $7 million grant.

The consortium includes about 50 staff, students and post-doctoral fellows from 24 institutions in five countries. About 25 of the participants are at UW-Madison.

The consortium has been tasked with finding footprints of biological activity, or biosignatures, which are substances such as elements or isotopes that show evidence of ancient life. The scientists are looking for microscopic signs of life, including microbes, which are bacteria, and other tiny, one-celled organisms that are much more adaptable than more complex organisms.

The team is also sending microbes into Earth's orbit on the International Space Station to see how they react to radiation and a space environment.

In the process, they are learning more about Earth's history. They've found new details of microbial life that dates back 2 billion to 3 billion years, before the planet's atmosphere contained oxygen. They've found that microbes then relied more on iron than sunlight for energy.

Eventually their work will be used to interpret data brought back from Mars by the six-wheel spacecraft Curiosity, which landed in August on a two-year mission to determine whether the environment was ever favorable for microbial life. Their work will also be used to prepare for future Mars missions.

"It may be that planets spent a long time in a microbial life condition and then only rarely evolved to advanced multicellular complex life," Johnson said. "That's one of the hypothesis we would test."

Edward Goolish, acting director at the NASA Astrobiology Institute, said the project supports one of NASA's major goals to find life or the potential for life elsewhere.

The project's results will provide a quantitative understanding of how life is preserved, he said.

"At the same time (Johnson's team is) contributing an immense amount to the understanding of life on Earth, which is equally important to astrobiology and science in general," he said.

Synthetic circuit allows dialing gene expression up or down in human cells

Feb. 11, 2013 ? Scientists who built a synthetic gene circuit that allowed for the precise tuning of a gene's expression in yeast have now refined this new research tool to work in human cells, according to research published online in Nature Communications.

"Using this circuit, you can turn a gene from completely off to completely on and anywhere between those two extremes in each cell at once. It's a nice tool if you want to know what happens at intermediate levels of gene expression. There has been no such system so far, but now it is available for mammalian cell research," said senior author G?bor Bal?zsi, Ph.D., associate professor in The University of Texas MD Anderson Cancer Center Department of Systems Biology.

Present options for altering gene expression in human cells are blunt instruments by comparison. Knocking out a gene eliminates its expression completely. Inhibiting it with RNA interference dials it partially down and can affect other genes. Inserting a gene expression vector into cells overexpresses the gene, but it's usually uncontrolled. Commercially available versions can switch a gene on or off, but cannot precisely dial between these extremes.

"For cancer research, the system will allow scientists to test the boundaries of a gene known to confer resistance to a drug in cancer cells by dialing its expression to different levels and treating the cells with the drug," said first author Dmitry Nevozhay, M.D. Ph.D., instructor in Systems Biology.

"Likewise, such a system would allow personalized gene therapy, by precisely tuning the therapeutic gene level expression depending on disease progression and the patient's need," Nevozhay said.

In microbial or yeast biology research scientists have started to understand and manipulate gene function quantitatively, almost like we understand electronic circuits, Bal?zsi said. "This makes research in those areas more amenable to engineering and mathematical characterization, -- but that's not true for human cells, and part of the problem is that tools that tune gene expression have been lacking."

A step-by-step guide for others to build mammalian synthetic gene circuits By refining their circuit to work in a human breast cancer cell line, the team demonstrated that their approach can be used in mammalian cells while offering a step-by-step guide that other researchers could follow to build other synthetic circuits for use with other genes.

"With all of our steps reported, if someone wants to build another type of gene expression switch, or oscillator, they could build the circuit in fast-growing yeast cells, where it can be engineered and optimized quickly and reliably," Bal?zsi said. "Once you know it works in yeast, you know the steps to make it function in human cells. This process is similar to extensive testing of NASA's space operations on Earth before actually carrying them out in space."

Synthetic biologists apply engineering principles to design and build new biological systems for predefined purposes.

In yeast, Bal?zsi and colleagues synthesized a gene circuit designed to control the level of gene expression precisely using the tetracycline repressor.

They made the promoter for the repressor identical to the promoter for the reporter gene yEGFP encoding the green fluorescent protein. This caused a negative feedback loop, creating a linear dependence of the yEGFP level on the tetracycline analog in the growth medium.

Tunable control of gene expression in mammalian cells

The researchers modified the synthetic network, which initially did not work at all in human cells. A computational model suggested a strategy to optimize the network for mammalian cells.

Several modifications improving transcription, translation and intracellular localization of the regulator protein were added to the synthetic network one at a time. Each one bolstered the network's output in human cells, until it finally achieved a linear dose response of gene expression to the tetracycline analog doxycycline.

Among the additions made to the circuit:

* Addition of an intron (non-coding DNA), which when inserted into genes can increase their expression in mammalian cells.

* Codon optimization in the repressor and reporter genes.

* Introduction of a nuclear-localization sequence, to take the circuit into the cell nucleus, where it can influence gene expression.

* Addition of the Kozak sequence, which improves gene expression in mammalian cells by enhancing translation.

* Promoter optimization, which maximizes the gap between full and basal expression.

Finally, they used the same circuit to control expression of an additional red fluorescence protein gene called mCherry as proof of concept for regulating other genes.

His synthetic gene circuit research won Bal?zsi a National Institutes of Health New Innovator Award in 2009, one of only 54 such grants made nationally that year to fund bold ideas with the potential to quickly translate research into improved human health.

"This research is not possible without the New Innovator Award," Bal?zsi said. "It allows you to explore off the beaten path. We aren't looking directly at the next obvious step towards curing cancer or discovering new molecular interactions.

"Yet, we believe steps that don't seem obvious today are crucial for tomorrow's therapies. We've outlined a set of engineering steps that will help us better understand and control gene expression to improve cancer treatment or develop new approaches to gene therapy," he said. "Traditional funding mechanisms would not have done it."

He also received an MD Anderson seed grant to launch his research.

Co-authors with Bal?zsi and Nevozhay is Tomasz Zal, Ph.D., of MD Anderson's Departments of Immunology and of Molecular and Cellular Oncology.

Research was funded by the NIH Director's New Innovator Award (1DP2 OD006481-01), a grant from the National Cancer Institute (R01 CA137059) and an MD Anderson Institutional Research Grant.
